Abstract: This paper presents concept of S-Rough Information Matrix.Using this concept,this paper puts forward single direction S-rough information matrix,both-direction S-rough information matrix and presents the mathematics structure of S-rough information matrix.S-rough information matrix is a new theoretical tool of studying system dynamical approximate characteristic,knowledge mining and knowledge discovery.

摘要： 提出了S-粗信息矩阵的概念。并讨论了单向S-粗信息矩阵,双向S-粗信息矩阵;给出了S-粗信息矩阵的结构特征。S-粗信息矩阵不仅是研究系统动态近似特征,而且是知识挖掘、知识发现的一个新的理论工具。
